Fix Up or Sell and Start Fresh

[Uzagonner]

Bought a 2009 sport 6MT Magnetic Black 370 about a year ago, and am now approaching the 100k mileage bump. Have been contemplating selling and buying a 2017 version. Most of the mods on my car were done by the previous owner and I have found little problems here and there that are bothersome, not to mention the cosmetic problems. In need of new headlights, a repaint. Curious on what y'all think, should I keep moding a high mileage Z or start fresh?
